Wintering Frogs

I live in Delaware. I have a backyard pond and was wondering how to best winter the frogs that are in the pond. Do I need to provide anything special?

It depends on several factors including the size of your pond, and the type of frogs involved. Some species will want to spend the winter underwater, buried in muck and decaying organic matter. Frogs of this type will probably survive at the bottom of a muck free pond as long as it is deep enough not to freeze all the way through. Other types of frogs will leave the pond and spend the winter in burrows or other sheltered locations on land.
